US Patent 12022884 Aerosol generating device and operation method thereof

An aerosol generating device includes a heater configured to heat an aerosol generating substrate, at least one sensor configured to sense a tap input of a user, and a controller configured to receive a sensing value indicating the tap input from the at least one sensor, count a number of tap inputs based on the received sensing value being greater than a variable threshold, and operate the heater based on whether the counted number of tap inputs reaches a predetermined input number, wherein the controller adjusts the variable threshold based on the counted number of tap inputs.
